So, her best friend is Selena Gomez and her  “boys” are the Jonas Brothers, but there’s much more to Demi Lovato than the singing-and-acting sensation made famous by Camp Rock and her debut album, Don’t Forget.

The 16-year-old beauty, who can’t live without her BlackBerry, has a dog named Bailey and is the middle child of two sisters, ages 20 and 6. Her full name is Demetria, her nickname is Dem, and she doesn’t remember the last time she was grounded. “My parents and I are very close,” she says. “It’s been a long time.”

What’s her tour must-have?

“It’s a blow-dryer for my hair. When I get offstage, I’m sweating like a dog, so I’ll probably need to blow-dry my hair because it’ll be wet.”

She calls out Hayley Williams of Paramore as her fashion plate. “She has great style in her videos. I look up to her.” She tells me she hopes to be “the girl version of the Jonas Brothers” in the style department, but beautywise she looks no further than her mirror.

“I like to try and emphasize what I have, and not really look at other people,” she says.

But Demi isn’t shy about giving props to her Disney Channel role models.

“Definitely Hilary Duff because she carried out a great career and she’s still going. And Christina Aguilera. She was on Mickey Mouse Club, and look at her now.  She’s gotten so far.”
 
What does Demi want to be when she grows up?

“When I really, really grow up, I would like to continue this and also work as a director and continue writing.”

Angelina Jolie, Oprah Winfrey, Russell Simmons and Scarlett Johansson got their wish as Barack Obama claimed a historic victory in his bid for president last night.

When asked what celebrity would make the best president at the W. premiere a few weeks ago, Russell was passionate Baracking the vote.

“Obama’s got a whole shift in economic policy -- the idea of trickling up versus trickling down,” he tells me that evening. “The Humane Society supports Obama. The greatest cause of global warming is farm animals, and the idea of dialogue around the world is important. The cosmic result of all our bad foreign policy is something we have to shift, so I think he’d be very good.”

Sure thing, Russell was the first person to e-mail me moments after Obama became the first African-American president elected. I caught Oprah and Jesse Jackson tearing up at his victory bash.

“Obama’s election as president is a beautiful testament to the American collective consciousness that is flowering,” Russell writes to me. “This more loving consciousness will be necessary to protect us from some of our hurtful human choices and tendencies. We will need it to create balance with the constantly emerging advances in technology so we can use these advances in a positive way to lift up Mother Earth and all her inhabitants.”

Onward and upward!

As Americans head to the polls in droves to vote for either John McCain or Barack Obama, we imagine a world where movie stars hold the executive office. After all, Ronald Reagan did it – why couldn’t Angelina Jolie?

George Clooney, 47, would get Cedric The Entertainer’s vote.

“He’s really fun and he’s real laid back,” Cedric tells me. “He’s just that cool dude. He’s got the swagger and he’s got a fun attitude. Plus, he’s got a bunch of cool friends, so then the cabinet would be off-the-chain, and the parties would be hot.”

The ideal First Lady for George is Scarlett Johansson, Cedric tells me. Nevermind that she’s married to Ryan Reynolds.

“You’d be like ‘yeah, that’s the First Lady, let her talk for a minute. Move George, let her say something.’ You’ve gotta do someone to balance him out that would be hot.”

Alas, George says he has trouble bringing two feuding sides together – case in point during the writers’ strike that took place earlier this year.

“It’s always hard to get people in the room to mediate anything,” Clooney admits.
 
Who else could rock the White House?
 
According to Michael Gaston, who appears in Body of Lies and W., Meryl Streep, 59, would make a great prez. “She’s one of the smartest persons I’ve ever known, incredibly empathetic and she’s got nerves of steel.”

Happy voting.

Daniel Radcliffe has grown up as Harry Potter, but now he’s transitioned into an adult role in Broadway’s Equus.

The 19-year-old actor talks about his Potter costars Rupert Grint, 20, and Emma Watson, 18, the end of Harry Potter and shares a quirky interest.

How did you feel about Emma being hesitant to sign on for more Harry Potter?
I completed my education and she was going into A-Levels. I think they’re called SATs over here? It’s a hard decision to further your education. I totally understood. She really thought about it. She wanted to weigh her options. It would be two or three more years. It’s not something to rush into lightly.

I’m 19 now, and I still have the energy of a four-year-old. I don’t have fatigue. For me, it would be very hard to see someone else do it – especially if he was cute. Also, I’d come this far…

How will you celebrate the end of Harry Potter?
We’ll have a massive party. We haven’t had any wrap parties, which I think is sinful. We haven’t gotten around to organizing. We’ll probably go out on holiday and do all the stuff the insurance hasn’t covered like rock-climbing and handgliding.

Is it true that you’re a World War I buff?
I always had an interest. I find it impressive. I’m the least militant, aggressive person you’ll ever meet. It was machines and machinism with warfare. I get periodically depressed by World War I. It's so sad they had to live like this. It’s mindblowing.

Catch Daniel in Equus, which is on Broadway now.
